f1785b0e4a spectrum: only scale the vectors that we are processing 
Phase is not produced by default, so lets not scale it unconditionally to save a
few cycles.

5bf267c485 spectrum: put number of channels to instance variable 
When freeing data the format might have changed. Thus we need to remember for
which format we allocated memory.

b792b100e2 spectrum: use function pointers for data readers 
Don't check the format for each sample frame to read. We can make that decission
in _setup already. This is still not ideal as we call the function per frame.
Ideally we determine how many samples we can copy and have a loop in the input
reader. As an alternative we might also consider to use the fft variants for the
various formats and not convert to float for all cases - we would still need to
mix or deinterleave though.

2738917852 rtspsrc: improve recovery from failed seek 
In case server-side fails to perform seek, i.e. PLAY at non-zero requested
position, recovery so far would arrange for streaming to continue, albeit
having lost position tracking in the process.  So, query position prior
to seek and use upon failed seek.

c622477a92 spectrum: multi-channel support 
Add a boolean multi-channel property with a default of FALSE. When set to TRUE
the element won't mix all input channels to mono, but instead run a FFT on each
channel. In that case the result message would contain a 2 dimensional array
of channel x data for magnitude and phase.

API: GstSpectrum:multi-channel

65f4c4b3e6 spectrum: factor out the code that accumulated samples into the ring-buffer 
Use a separate function to read a sample frame into a ringbuffer slot. In the
future we can use format-specific function pointer to avoid the reoccuring
format checks.

787aca6898 spectrum: add a GstSpecrtumChannel context structure 
We now keep the fft data that is related to one channel in a separate structure
to prepare for multichannel support. We also refactor the code to operate more
often on the channel context.

That is, in case of short (or near eos of) stream, deadlock (until timeout)

06972db7b6 icydemux: fix tag list handling issues that might have caused crashes 
Fix slightly confused tag handling in some places: make it clear when
we're taking ownership of a tag list and when not. For example,
gst_icydemux_tag_found() was taking ownership when the source pad
existed, but otherwise not (leak). Also, gst_event_parse_tag() does
not return a newly-allocated taglist, but a tag list that belongs to
the tag event, so don't give ownership of it away.

While we're at it, some minor clean-ups: don't re-invent g_strndup()
and simplify gst_icydemux_parse_and_send_tags() a bit, and don't
leak the tag list in case no valid tags where found.
